To provide a passage opening/closing device which can suppress self-excited vibration of a slide door while suppressing deterioration in slide door manufacturability.SOLUTION: A passage opening/closing device comprises a case 12 in which a cold air passage 22 is provided, and an air mix door 50 which is slidably located in the case 12 and opens/closes a cold air opening part 22a. The air mix door 50 includes a cold air side end part 52A which faces a cold air opening marginal part 23 when the air mix door 50 is displaced to a closed position of the cold air opening part 22a. The cold air opening marginal part 23 faces the cold air side end part 52A when the air mix door 50 is displaced to the closed position, and includes, between itself and the cold air side end part 52A, a cold air seal portion 126 which forms a gap flow channel G extending along a door movement direction. With respect to the cold air side end part 52A and the cold air seal portion 126, an interval between the cold air side end part 52A and the cold air seal portion 126 becomes smaller toward an air flow downstream side so that the gap flow channel G becomes a tapered flow channel.SELECTED DRAWING: Figure 1

    【課題】スライドドアの製造性の悪化を抑えつつ、スライドドアの自励振動を抑制可能な通路開閉装置を提供する。【解決手段】通路開閉装置は、冷風通路22が内部に設けられたケース12と、ケース12の内部にスライド移動可能に配置されて冷風開口部22aを開閉するエアミックスドア50と、を備える。エアミックスドア50は、エアミックスドア50が冷風開口部22aの閉鎖位置に変位すると冷風開口縁部23に対向する冷風側端部52Aを含む。冷風開口縁部23は、エアミックスドア50が閉鎖位置に変位した際に冷風側端部52Aに対向するとともに冷風側端部52Aとの間にドア移動方向に沿って延びる隙間流路Gを形成する冷風シール部126を含む。冷風側端部52Aおよび冷風シール部126は、隙間流路Gが先細り流路となるように、冷風側端部52Aと冷風シール部126との間隔が空気流れ下流側に向かって小さくなっている。【選択図】図1
